SIGNAL CLOCK.

Application filed September 7, 1921. Serial No. 499,066.

- better than where concealed or closed for the work by its upper part or neck to provide space around said dial for a number of.

switches, which receive the electric current from the rear of said dial.

Third, the automatic closing of the circuit with an operating lever and to open said circuit by stopping said clock with said lever.

Fourth, adjusting means on each of the switches, to close the circuit to each switch for the length of time required.

Fifth, a signal clock provided with a dial having its running numbers in a straight line, a series of switches arranged for moving in a parallel direction to said numbers and a bridging contact carried by the clock driving mechanism in said direction to operate said switches. I attain these objects by the mechanism illustrated in the accompanying drawings, in

which- I Figure I is a device.

Fig. IV a, front view of a modification of said switch device in a straight form, showing a series of switches arranged for adjustment in a straight direction and a rack, operated by a gear wheel and secured to the main shaft of the clock work to carry the arm with its bridging contact in the same direction to operate said switches. a

Fig. V is a cross sectional view of a switch for showing the hollow arm.

in two parts, C and C A clutch D is sethe operator.

to the switches by the starting of the clock Similar letters refer to similar parts throughout the several views. A dial A is secured by its upper part or neck to the casing or frame work. A shaft C is cured to the shaft G and is meshed to a clutch DD which is slidably arranged on the shaft C A rail I is secured to said shaft which fits into a corresponding opening in the clutch DD to connect or disconnect the shafts, as shown by the dotted line position of said clutch. A lever B shown in two positions is secured to said clutch for moving clutch DD into engagement with clutch D by the will of A spring E is secured to the shaft C and the casing to return the arm F when the same is released from the clutch DD to itsfixed position against a pin not lettered which is secured to the dial- A number of switches G, a separate view of one is shown in Fig. II, are movably arranged on a rim which surrounds the dial A. Said switch is in two parts, part-1 is secured by a spring button G to the grooves G in said rim, the part 2 is movably arranged in guide rail G secured to part 1. A screw H in part 2 is arranged for moving both parts nearer or further apart. One contact J is secured in each part of the switch and the conductors therefore are arranged in the hollo-w part of the switch supports K- shown in Fig. V. The lower parts of said supports for all the switches are arranged in a suitable manner in the rear of the dial around the shaft C to allow the turning of said. switches to diflerent positions around said dial. The arm F is secured to said shaft and carries on its upper part a bridging contact L, shown in Fig. III. Suitable springs between said to give said contact a good connection with the contacts J when the arm is operated by the clock work. A stand or frame M consisting of h ard rubber is stationarily arranged in the rear of the dial, said stand is provided for carrying a number of circular contacts. Each one of the switch supports K carries a contact K which is arranged in the rear part of said support and which must be in contact with the outer circular contact N, arranged for leading the electric current to all the switches. A second contact K in said rear part of the support K is arranged to press on and be in connection with one of the inner circular contacts N in such amanner ill) that each one of the switches is attached to the next contact N for leading the current from each one of the switches in a dilierent direction to be used for a different purpose. Current conductors are arranged in the inner side of the switch supports K, a current conductor K to close the circuit between the contacts K and J and a conductor K between the contacts K and J A stop T can be secured in diiicrent positions around the dial, by securing said stop in the rear of a switch it operates said switch till the arm is returned to its fixed position by pulling the lever B.

The clock work which operates the electric device being connected through the shafts The upper part of said clock is a paddle wheel O, the size of the paddles must be in proportion to give the right air-resistance for the movement of the arm around the dial required; at the lower part of said clockwork is a spring or a weigl'it P. A chain of gears and pin wheels connects said paddle wheel with said spring.

A signal clock having a series of switches arranged for moving in a straight direction is shown in Fig. IV. Two guide rails Q, arranged one on the top and one on the bottom of the dial A to provide means for moving the switches Gr in different positions. The arm F with its bridging contact L is secured to a rack R which is movably arranged in suitable supports. A gear wheel S is secured to the main shaft C of the clock work and is meshed to said rack R. hen the clockwork is in operation the arm is moved past the switches by said gear wheel S. A contact board U is inserted in the casing or frame work of the clock. A row of separate contacts U are secured in said board. Conductors U are arranged to lead the current separately through suitable openings in the rear of the hard rubber frame M from the contact U to the inner circular contacts N. Exchangeable contact boards U each one having difierent wiring are removably attached with two screws U to the contact board U. An exchangeable contact board U to operate one switch is shown in Fig. IV and for using all the switches one is shown in Fig. I.

The electric current is led to the device by the conductor V which closes the circuit with the outer circular contact N. The other end of said conductor V carries a contact V which is arranged on a stand V A contact W carrying a live wire IV is secured on the operating lever B in such a position to press on and be in connection with the contact V by the pressing of the operating lever B, a second position of said lever is shown in a dotted line.

The operation is as follows: The operator moves the lever B to start the clock thereby connecting the clutches D and DD and closes the circuit to the switch device by the contacts IV and V and by pulling said lever to its first position breaks said circuit and stops the operation of the clock.

The switches are moved to indicate the desired time of operation and secured in place by the spring button to the rim of the dial the different switches are adjusted with the screw I-I'for the length of time for closing the circuit on each switch required, then one of the exchangeable contact boards U is secured in position with the contact board U, the positive current is lead direct to the motor, an electric lamp, bell or to a trans lating device, the negative current is connected to the wire W and must go through the switches and then to the translating device The operation can be stopped at any moment by pulling the lever B to its first position, thereby opening the circuit to the device and releasing the arm which is returned by a spring to its first position.
